Optical switches are a common building block for many optical systems and have been proposed for a variety of future space applications, from building simple redundancy to providing fast isolation or modulation of light intensity. Solid-state switches greatly improve the reliability of existing optical switch technology compared to bulky mechanical switching systems. It is also capable of providing faster switching speeds, which are required for some optical switching applications.

Frequently Asked Question

Do you have any question?

The optical switch matrix is the core component of the optical network node equipment, which is responsible for the routing control of multi-channel signals. According to the principle and material, it can be divided into many categories. At present, the commercialization boom is mainly MEMS switches, which use electrostatic force to realize the deflection of micro lenses, and the switching time is generally in the order of milliseconds; there are also switches that use thermo-optic, acousto-optic and magneto-optic effects, and some products have been launched. And so on; semiconductor-based optical switches, which modulate the carrier concentration by current (electric field) injection or light injection, thereby modulating the refractive index of the material, realize switching, and the speed is on the order of nanoseconds, which can be applied to optical grouping Exchange (OPS).

According to the difference of manufacturing process and technology, optical switches can be divided into mechanical switches, MEMS switches, magneto-optical switches, etc. The first two switch types are the most widely used on the market today. In addition, thermo-optic switches, electro-optic switches, and acousto-optic switches are also used in some specific applications.
